"The sheets we go through…" the Aussie joked during a recent interview with The Sun. Added his wife of 17 years, Deborra-Lee Furness, "Oh my God, it’s dreadful! Always with the claws. I'm like, 'Mix the salad. Put them to use, come on!'" The actor, who has been portraying the character seven times since the start of the long-running X-Men franchise in 2000, jokes that he wears all the blades behind closed doors.

In fact, the actor wears the famed getup in other unexpected places, too. Jackman, 44, revealed that he dressed as wolverine during Comic-Con in San Diego this month and no one even noticed. "I got dressed up in my full Wolverine costume. Not one person stopped me," he announced to the crowd. "One guy goes, 'Eh, not bad.' And another one said, 'Whoa. Way too tall buddy.'"

Jackman, of course, gets plenty of comments for what he looks like without much on at all—and getting that famously muscular bod is hard work, he has said. "You actually have to eat a lot, and I'm quite a skinny person," he said during a Sirius XM satellite radio interview in May 2013. "What I do is I eat in an eight hour period, it's all the rage this diet now. It's called the 16-8 diet. For sixteen hours of the day, I fast, so I don't eat. Between ten in the morning and six o'clock at night … I eat 5,000 calories and then I eat nothing." Adding, "I literally talk to myself like I’m training: 'One more mouthful, come on man, you can do it. Just one more mouthful. Half a chicken breast to go and you’ve got it! Only two meals left.'"
